The plates are interconnected by a As shown in Fig. 1, three of these devices are linkage mechanism so that they are supported mounted at spaced points along the jamb. Each 5,0V at a plurality of points, preferably adjacent the device comprises a pair of plates Il and I8, which ends of the plates. With this construction, the in the preferred form, extend substantially the jamb is effectively prevented from pivoting about full width of the stud and jamb. These plates a vertical axis. Due to the interconnection of are interconnected by suitable linkage mechathe plates by a linkage mechanism, the plates nism for movement toward and away from one will. always more toward or away from one ananother. The linkage mechanism is so arranged that the plates always assume a deiinite relation to one another. In the preferred form, they insure that the plates will always remain in parallel relation.

The plates are provided adjacent their ends with a pair of outwardly extending ears 22 and 23 respectively which form a means for securing the linkage mechanism. The linkage mechanism comprises a pair of links 24 and 25, which are pivoted intermediate their ends by rivets 26. This construction forms a lazy tong connection between the two plates, with one of the ends of each arm being secured by suitable means to the upstanding ears 22 and 23 at one end of the plates. The ears extend outwardly from the plates and are provided with a at face which forms a suilicient bearing surface for the links 24 and 25 whereby a rigid connection is obtained in all adjustments of the device.

In the form of the invention shown in Figs. 2 through 4, stove bolts 21 have been used to connect the links to the ears at this end and the holes in the links are cut away so that the heads of the bolts will lie flush with the outer surface of the link. It is to be understood that atheaded rivets can be countersunk into the links in the same manner.'

The other ends of the links are provided with suitably shaped slots 29, 30 which engage projections extending outwardly from the ears 22 and 23 at the other ends of the plates.

As shown in Figs. 2 and 3, stove bolts or the like means form the projection on the latter ears and the sides of the slots 29, 3) are cut away as shown in Figs. 2 and 4 to permit the heads to be countersunk below the outer surface of the legs.

With this construction, the links are detachably held in place and can be released upon actuation of the adjusting means to permit the plates to open into an` extended position in which they can be readily secured to the stud and jamb.

Y In order that the plates can be readily adjusted toward and away from one another, an adjusting screw 33 is provided. 'I'he screw is formed with an elongate head 34 having a reduced portion` 35 and an outwardly extending shoulder 36. This end of the screw is interlocked with the plate I8 by being inserted in the slot 31 formed in the end of the plate thereof. The other plate is formed with a projection 28 into which the adjusting screw is threaded. With this construetion, rotation of the adjusting screw will move the plates toward or away from one another and the linkage mechanism will retain the plates in parallel relation and will afford adequate support for each end of the plate.

In assembling the jamb to the stud, a hole 40 is bored through the jamb and a metal liner 4I is inserted therein to protect the jamb from scarring when the screw driver or other tool is inserted to adjust the connecting mechanism. The iixed stud I is provided with a hole 42 positioned to receive the end of the adjusting screw.

When the stud and jamb have been prepared, the adjusting screw is interlocked with the plate I8 and the elongate head thereof is inserted into the metal lined hole 40. During this operation, the links are released from the screws 21 so that the two plates can be readily separated.

The plates Il and I8 are provided with apertures I9 through which wood screws 2U are sent into the stud and jamb to lock them in place. In the preferred method of using the adjusting means, the plate I8 is rst secured to the jamb for each of the adjusting devices. The jamb is then set upon the plates I'I are screwed to the iixed stud with the links still disconnected.

After the plates I1 have been rmly secured to the xed stud, the slots 29, 3D in the ends of the links are interlocked with the projections on the ears and the screws 33 is threaded into the projection 38 in the plate I'I. 'I'he links, when interlocked with the plate, will readily hold the jamb against pivotal movement about a vertical axis inasmuch as the cross links will support the jamb on the stud at a plurality of points. With this linkage construction, adjustments of the screw will move the jamb toward or away from the xed stud so that the jamb can then be adjusted to the proper vertical position to receive the door. While this procedure has been outlined for one of the jamb members, it can be duplicated on the other side jamb member so that the latter can be readily set in position to receive the door.

The adjusting means, as shown in Fig. 2, is so positioned that the hole 40 will be normally covered by the door when in closed position and will not in any way mar the appearance of the doorway. By this means, the door cannot be tampered with and forced open by adjusting the device and moving the jamb away from the door far enough to permit the keeper to be released from the usual latch mechanism of the door. The door must be open in order for adjustments toy be made.

By' having the jamb adjustably mounted, it can be moved at any time to correct for changes in the iit of the door. For example, should the door be made of seasoned material, and after a short usage become swollen due to the absorption of moisture so that it becomes impossible to close the same, the jamb can be readily adjusted so as to lit the door. On the other hand, should the door be made `of unseasoned material, which, after short usage, becomes dried out and shrinks, leaving an opening between the jamb and the door, which in some instances is sufficient to prevent the door from latching when closed, the jamb can be adjusted into proper relation with the door. These adjustments can be made without the necessity of removing the door and planing its edges or tearing down the framework to adjust it into proper position.

After the jambs have been properly positioned on the studs, the usual trim 43 around the door jamb is put in place. This can be done by being nailed in place to the fixed studs to intermediate blocks secured to the studs or any other preferred means.

The device of the present invention can be used to mount the jamb on which the door is hung. If it is used on the jambs on both sides of the opening, a large amount of adjustment can be made in order to oveicome swelling or shrinking of the door.

In the form of the invention shown in Figs. and 6, the links 24a and 25a, are pivoted together by rivet 26a and the ends thereof secured to the ears 22, 23 on the plates by means of rivets 48 provided with heads 49 overlying the outer surface of the links. The heads will provide, with the bearing on ears 22 and 23, a bearing on each side of the link. The links 24a and 25a are provided with slightly lateral offset portions 50 and 5I respectively, which form between them a recess at each end of the ends to accommodate the heads 49 overlying the outer surface of the linkage. This construction provides a very rugged and sturdy connection between the links and the plates, and, at the same time, permits the device to be collapsed to the point in which the links 24a, and 25a overlap at their end portions. The links in this form `of the invention are provided with suitably shaped slots 29a, 30a which engage the rivetsl 48 and can be assembled in the same manner as in the form of the invention shown in Figs. 2 to 4.

Variations and modifications may be made within the scope of this invention and portions of the improvements may be used without others,
